Littelfuse Introduces Circuit Protection Industry's First True High Power Surface Mount TVS
Diodes for Lower Production Costs
Surface mount SMTO-218 package is ideal for automatic pick and place assembly and reflow processes
CHICAGO, November 24, 2015 — Littelfuse, Inc., the global leader in circuit protection, has introduced two new product
series, the LTKAK6 and LTKAK10 Series TVS Diodes, designed to offer clamping characteristics superior to those of standard
silicon avalanche diode (SAD) technologies. This superior performance is made possible by Littelfuse Foldbak technology,
which provides a clamping voltage lower than the avalanche voltage but above the rated working voltage. As a result, any
voltage rise due to increased current conduction is minimized. Both products can be connected in series and/or parallel to
create a variety of flexible protection solutions. They provide the same enhanced quality, easy manufacturing and compact
mechanical design found in the company’s AK Series TVS Diode families. Additionally, because they are provided in a surface
mount SMTO-218 package, they allow circuit designers to save even more circuit board space. This surface mount package is
ideal for automatic pick and place assembly and reflow processes, allowing for a lower manufacturing cost and greater
soldering quality than axial leads packages.
Typical applications for the LTKAK6 and LTKAK10 Series TVS Diodes include transient overvoltage protection for cell phone
base stations, industrial transient voltage surge suppressors (TVSSs), railway (railroad) trackside signaling and control
cabinets, defense and avionics, and power grid and distribution systems.
“The LTKAK6 and LTKAK10 Series are the circuit protection industry’s first true surface mount high power TVS Diodes,” said
Jeff Chin, product line director for the TVS Diodes line. “They offer better voltage clamping performance and higher speed than
other solutions used in these applications, such as metal oxide varistors (MOVs).”
LTKAK6 and LTKAK10 Series TVS Diodes offer these key benefits:
●
●
●
●
LTKAK6 and LTKAK10 series in an innovative package (patent pending) design offers the highest power rating (8x20µs
waveform) among surface mount TVS available in current market
LTKAK6 and LTKAK10 series in a surface mount package is ideal for automatic pick and place assembly and reflow
processes, allowing for a lower manufacturing cost and greater soldering quality than axial leads packages.
Because LTKAK6 and LTKAK10 TVS Diodes can withstand multiple surge events, they will help equipment
manufacturers extend their product warranties because, unlike passive MOVs, these semiconductor TVS Diodes do not
wear out, which makes them ideal for protecting valuable loads.
These TVS Diodes are certified, environmentally friendly and suitable for worldwide usage that can help designers meet
global regulatory standards.
Availability
The LTKAK6 and LTKAK10 Series TVS Diodes are available in SMTO-218 surface mount packages and are sold in quantities of 400 in tape-andreel packaging or quantities of 100 in tube pack (25 per tube). Sample requests can be placed through authorized Littelfuse distributors worldwide.
